IMPROVEMENT IN WIND AND TIDE-ALARMS.

The Schedule referred to in these LetterePatent and making part of the same.

To all whom it may concern:

Be it known that we, GEORGE M. HOFFMAN and PETER HERMAS, Jr., of Rahway, in the county of Union, and State of New Jersey, have invented a new and useful \Vind and Tide-Alarm for Sailing- Vessels; and we do hereby declare that the following is a full, clear, and exact description of the same,

reference being had to the accompanying drawings, which form part of this specification.

This invention is especially designed for use on ships and other sailing-vessels, but may be applicable to other purposes.

I Its object is to give notice to the crews of such vessels, while asleep, of the change of wind or tide; and to this end,

The invention consists in an alarm-movement connected with the vessel, and having a novel locking and tripping-attachment operated through the medium of a-connecting-cord and a sinker, resting at the bottomof the body of water, whereby, when the vessel moves, the cord is tightened, and the alarm set in motion by the tripping oi the device.

Referring to theaccompanying drawings- Figures 1 and 2 represent a side and an edge view of a wind and tide-alarm, for ships and other sailingvessels, constructed according to our invention, and

Figure- 3, a view taken at right angles to fig. 2.

Similarletters of reference indicate corresponding parts. in the several-figures. v

A re resents the alarm-movement, constructed substantially in the usual way, and secured to a bed-plate, B, to which is also secured the hell 0.

Projecting from the rocking shaft of the bell-hammer' h-,'of,the said alarm-movement, is an arm, a, which eitt'ends beyond the limits of the alarm-movement, and

nearly or quite at right angles to the shank of the ham r," its outer end terminating within the lim-- its 'iifl-a locking-frame, D.

Said frame D is also secured to the bed-plate B, near the alarm-movement, and in which is contained a lever, b, which looks with the arm a, of the hammershaft, to hold the same, and prevent the oscillatory movements of the said hammer while it is not desired to act. Y

This lever 11 is pivoted, by one end, to the base of the said locking-frame D, and made to pass through a slot, 0, formed in'the opposite side of said frame, so as, by sliding outwardly or from the alarm-movement A, to swingbeyond the reach of the extremity of the arm a, and disengage from the same. It is also provided at its outer end with a ring or loop, in which issecured a cord, f.

This cord f, passing through any number of suitably-arranged guide-rings (I, is supplied, at its opposite extremity, with a weight or sinker, H, which is passed over the side of the vessel into the water, and allowed to sink to the bottom, so that the removal of the vessel to a sufficient distance, while the said weight remains stationary at the bottom of the water, causes the tightening of the cord f, which serves to draw the outer porton of the locking-lever I) along the slot 0 to a point beyond the extremity of the arm a, thus releasing the alarm A. y

The said slot 0 may be formed with a recess at or near its inner extremity, for the reception of the locking-lever I) while looking thealarm, so as thereby to prevent the unlocking of the same by any slight force. This alarm maybe suspended, bymeans of the rings S S, from the walls of the sleeping-apartment, or

from any other desirable portion of the vessel, and the cord f, which may he of any desirable length, conducted throngh guide-rings to the stem or other part of the boat, where it is desired to cast the weight, so that when the tide or the wind changes, the same 'will, by drifting the vessel, cause the announcement of thezfact from the alarm.

What we claim as ourinvention, and desire to have' secured by Letters Patent, is-

The combination, with the alarm A, of the locking and tripping-lever 1), arranged for operation, as described, in connection with the connecting-cord f and the sinker H, whereby the said alarm is released by the drifting or change of position of the boat, substantially as set forth.
